1、Designation: D3652/D3652M 01 (Reapproved 2012)Standard Test Method forThickness of Pressure-Sensitive Tapes1This standard is issued under the fixed designation D3652/D3652M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year
2、of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method covers the determ
3、ination of the thick-ness of pressure-sensitive tapes at standard conditions.1.2 This test method is intended to replace AFERA 40062and PSTC 33.21.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equ

Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user
5、of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Apparatus5.1 Cailper Gage, with the following requirements:5.1.1 Two plain faces, the smaller of which is circular and 8to 16 mm 0.32 to 0.64 in. in diameter. The faces shall beparallel to within 0.005 mm 0.0002 in. and constrained tomove apart along an axi
